MACHINE FOB BURNISHING- THE EDGES OF THE SOLES OF BOOTS AND SHOES.

Specification of Letters Patent.

Application filed August 3, 1911. Serial No. 642,147.

To all whom it may concern Be it known that 1, ZOTIQUE BEAUDRY, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented new and useful Improvements in Machines for Burnishing the Edges of the Sol-es of Boots and Shoes, of which the following is a specification.

This invention relates to an improved machine for burnishing the edges of the soles of boots and shoes. the invention being particularly directed to an improvement in the burnishing irons and the manner in which they are carried by the reciprocatory member of the machine and presented to the edge of the sole to be burnished.

The object of the invention is to provide a machine in which the burnishing iron or irons are so supported that they will rock readily to accommodate themselves to the varying curves of the sole of a shoe, either longitudinally of the edge of the sole or laterally thereof, so that the working face of the burnishing iron or burnishing irons will be presented to all the different parts of the edge of the sole in substantially the same relative position.

In the preferred embodiment of my invention I utilize a mechanism for imparting a reciprocatory or rocking movement to the burnishing irons similar to that illustrated and described in U. S. Letters Patent issued to me August 17, 1909, No. 931,558, to which reference may be had as illustrative of a machine in which my improved burnishing irons and their supporting members may be utilized.

T he invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.

Referring to the drawings: Figure 1 is a left hand side elevation of a portion of a sole edge burnishing machine similar to that illustrated in said Letters Patent, with my improved burnishing irons and their supporting members and carriers illustrated in connection therewith. Fig. 2 is a front elevation of the burnishing irons, their supporters and carriers, the same being drawn to a scale about full size as used in practice.

Fig. 3 is a side elevation of the burnishing irons for the edges of the fore part and of the shank of the shoe, illustrating the same in connection with their different holders and carriers and the main support upon which both fore part and shank irons are mounted. Fig. 4 is a sectional elevation taken on line 44 of Fig. 2. Fig. 5 is a front elevation of the shank burnishing iron and its support and holder as viewed from the left of Fig. 3. Fig. 6 is a sectional elevation taken on line 66 of Fig. 2. Fig. 7 is a front elevation of one of the edge burnishing irons. Fig. 8 is an underneath plan of the same. Fig. 9 is a sectional elevation illustrating a modified form of burnishing iron together with a portion of its holder, the iron being shown in elevation and the holder being shown in sect-ion and broken away to save space in the drawings. Fig. 10 is a front elevation of amodified form of burnishing iron.

Like numerals refer to like parts through out the several views of the drawings.

In the drawings. Fig. 1, 10 is the frame of the burnishing machine in which is ournaled a driving shaft 11 having fastened to the front end thereof an eccentric 12. The eccentric 12 is connected by an arm 18 to an arm 14 on a rocker frame 15. The rocker frame 15 is journaled to rock upon a shaft 16 fast to the frame 10 and has a clownwardly depending arm 17 in which is journaled the shank 18 of a tool carrier support 19. A collar 20 is fastened to the upper end of the shank 18 and a cross-bar 21 extends transversely of the shank 18 at its lower end and fits in a slot or groove 22 in the lower end of the arm 17. The tool carrier support 19 is moved downwardly so that the cross-bar 21 moves out of the groove 22 and is rotated to bring the fore part burnishing irons toward the front of the machine in readiness for operation upon the fore part of the edge of the boot or shoe sole, or the same is rotated to bring the shank burnishing iron toward the front of the machine in order that the same may be utilized for burnishing the shank portion of the edge of the boot or shoe sole, as may be desired, by mechanism fully described and shown in said Patent No. 931,558, but not shown in Patented Deed), 1913. v

the drawings of the present application, as the same is not considered an essential portion of the machine of this invention.

Referring to Figs. 1 to 7 inclusive of the drawings, 23, 23 are the fore part burnishing irons, each of said irons, respectively, being pivoted upon a pin 2-4 and 24, con stituting a pivot therefor, said pins being fastened to ears 33, 33 on holders 25, 25, said holders being pivoted to rock upon pivotal pins 26, 26 fast to a carrier 27. The carrier 27 is pivoted on a stud 28 which, in its turn, is fastened to a holder 29, the holder 29 being pivoted upon a stud 30 fast to the cross-bar 21 of the tool carrier support 19.

It will be understood that the shaft 11 and eccentric 12 impart, through the arm 13, a rocking motion to the rocker frame 15 and, therefore, a rocking motion is imparted to the tool carrier support 19 and the parts carried thereby, including the burnishing irons, their holders, the pivoted carrier 27 and its holder 29. The path of travel of the burnishing irons and their holders is longitudinally of the edge of the sole 31 of the shoe 32 being operated upon, and the pivotal axial line of the fore part burnishing irons extends transversely of the pathof travel of said irons and of the carrier 27. The pivotal axial line of the carrier 27 or of the stud 28 also extends transversely of the path of travel of said carrier and is located in a plane extending transversely of the path of travel of and between the burnishing irons 23, 23. 'he pivotal axial lines of the holders 25, 25, on the contrary, extend at right angles to the pivotal axial lines of the burnishing irons 23. 23 and preferably intersect said pivotal axial lines. The pivotal axial lines of eacn burnishing iron and its respective holder are substantially parallel to a plane extending transversely of the path of travel of said iron and also extending substantially at right angles to the working face of said burnishing iron when the latter is in its central position. The pivotal axial line of the holder 29 is also at right angles to the pivotal axial line of the carrier 27' and inter-- sects said pivotal axial line.

The irons 23, 23 are prevented from rocking beyond a certain angle in one direction by a shoulder 3% on the upper edge thereof which abuts against the lower edge of the holders 25, 25, while in the other direction the said irons are prevented from rocking beyond a predetermined angle by the upper edge 35 of said burnishing-irons which engages the lower edge of the holders 25, 25, as will be clearly seen by reference to. Fig. 2.

The means hereinbefore recited for preventing the rocking of the irons beyond a predetermined angle are operative only when the irons are not in use. When they are in use they will be prevented from rocking to an abnormal extent by the fact that portions of the bed face of the burnishing irons on opposite sides, respectively, of a plane extending transversely of, intersecting and at right angles to the working face of the burnishing irons are adapted to contact simultaneously with parts of a straight sole edge located at a substantial distance apart longitudinally of said sole edge, as contrasted with a convex bed face. This form of bed face assures the rubbing action of the iron upon the edge of the sole as distinguished from a rotary action about its pivot and a rolling action upon the edgeof the sole.

The burnishing irons 23, 23 are preferably corrugated upon their working faces 36, 36, the burnishing iron 23 having substantially a smooth face 36, but, preferably, a single corrugation, as 37, (see Fig. 2) while the burnishing iron 23 has upon its working face 36 a plurality of corrugations 37, 37. Tie object of this construction that is, in having more corrugations in the working face of the burnishing iron 23 than in that of the burnishing iron 23 is that the burnishing iron 23 is in advance of the burnishing iron 23 as the work is being done upon the edge of the sole and the shoe is being moved in the direction of the arrow 6 in Fig. 2 relatively to the burnishing irons 23 and 23, so that the work first comes along the edge of the sole to the burnishing iron 23 and later to the burnishing iron 23, and thus the burnishing iron 23 does the rougher work first, so to speak, while the burnishing iron 23 does the smoother and more highly finished work of the edge burnishing.

Vhere a single burnishing iron is used, I prefer to use the form illustrated in Fig. 10 in which the same principle hereinbefore set forth is carried out in a single iron-that is, r

the burnishing iron which the work first approaches is made corrugated, while that which follows up with the smoother work and a higher degree of polish is performed by the smooth portion 61 of the working face of the burnishing iron.

Said burnishing irons are locked in position against longitudinal movement upon their respective pivotal pins by T-shaped slide latches 37 37 each arranged to slide in ways 38 upon its respective holder and held downwardly in position to look its respective burnishing iron upon the pivotal pins bysprings 39, 39 which are fastened to the holders 25, 25, by screws 40. Said springs are coiled about the screws 10 and terminate at one end in the holders 25, 25,

and at the other end rest upon screws 41, 41 fast to the T-shaped slide latches 37 37 The downward movement of these T-shaped slide latches is limited by the cross-bar 42 which abuts against the cars 43, 43 on the holders 25, 25 when the T-shaped latch has been pushed downwardly to a sufficient extent to lock the burnishing irons against longitudinal movement on their respective pivot-s.

The holders 25, 25 are each prevented from rocking beyond a predetermined angle, respectively, by the screw 40 which is fast to the holder and passes through a hole 44 of larger diameter than said screw at the back of the pivotal stud 26 or 26, so that when the holder is rocked to a certain angle in either direction the screw 40 will abut against the stud 26 or 26' and stop said holder from being rotated or rocked beyond that angle.

The carrier 27 is prevented from rocking beyond a predetermined angle by the holders 25, 25 which abut against the holder 29 when said carrier is rocked to a certain angle in opposite directions, and thus prevent the same from being rocked beyond such angle. The holder 29 of the carrier 27 is prevented from being rocked upon its pivotal stud 3O beyond a certain predetermined angle in either direction by a screw 45 fast to said holder and projecting through a hole 46 in the stud 30, said hole being of greater diameter than the screw 45, so that when the holder 29 is rocked to a certain angle in either direction, said screw 45 will abut against the stud 30 and prevent said holder from being rocked beyond that angle. The holder 29 is maintained in a substantially central position, together with the carrier 27, by means of a spring 47, one end of which is fastened to a screw 48 fast to the cross-bar 21, and the other end to a screw 49 fast to the holder 29.

In the burnishing iron 23 at the right of Fig. 2, the pivotal stud 24 is illustrated as extending entirely through said burnishing iron. 1n the burnishing iron 23 at the left of said Fig. 2, the burnishing iron is illustrated with a stud 24 which extends only partly therethrough as illustrated in Fig. 6.

The shank burnishing iron 50 (Figs. 4 and 5) is pivoted upon a stud 51 fastened to a holder 52, the holder 52 being pivoted upon a stud 53 fast to the cross-bar 21. A screw 54 fast to the holder 52 prevents said holder 52 from rocking beyond a predetermined angle, the same as in the fore part irons and the iron is held in position upon its pin by a slide latch 55, substantially the same as the form of slide latch hereinbefore described for holding the fore part irons upon their respective pivotal pins.

It will be seen that the pivotal axial line of the burnishing iron 50 will extend transversely of the path of travel of said burnishing iron and of its holder 52 and that the pivotal axial line of the holder 52 extends at right angles to the pivotal axial line of the burnishing iron 50 and that these ivotal axial lines intersect each other.

It will be seen that in the mechanism for burnishing the edges of boots and shoes, it is very essential that the same should be so constructed that the burnishing irons for the fore part and for the shank may be readily removed from their pivots, in order that other burnishing irons having a different form or that new burnishing irons to replace old ones may be substituted, and in the construction hereinbefore described it will be seen that both the fore part and the shank burnishing irons may be very easily and quickly removed from their holders, either when said burnishing irons are pivoted upon pins fast to the holders as in Figs. 4 and 6, or when the pivotal pins are integral with the burnishing irons as illustrated in Fig. 9. All that it is necessary to do to remove the burnishing iron in the form illustrated in Figs. 4 and 6 from its holder is for the operator to raise the slide latch 37 by means of the screw 41 against the action of the spring 39, then slip the burnishing iron oif its pivot 24 and place a new burnishing iron on said pivot and release the latch slide, when it will be at once carried down by the spring 39 until the cross-bar 42 engages the ears 43 on the holder. In the form illustrated in Fig. 9 the operation of removing the iron is substantially the same as that hereinbefore described in relation to the removal of the iron illustrated in Figs. 4 and 6, except that the iron 56, together with its pivotal shank 58 is removed from its holder 57 by withdrawing the shank from the hole in the holder.

It will be seen that the pivotal axial line of the burnishing iron extends laterally of its working face and that when it is in position upon its holder, the ear 33 projects along the rear face of the burnishing iron and the latch slide is in engagement with the opposite face of said burnishing iron, whereby the same is prevented from accidentally becoming detached from its pivotal pin and from its holder.

The general operation of the mechanism hereinbefore specifically described is as follows: Assuming that it is desired to burnish the edge of the sole from the shank around the fore part, the burnishing irons 23 and 23 are utilized, and the tool carrier support is in the position illustrated in Fig. 1. The edge of the shoe sole is held by the operator against the burnishing irons 23 and 23 in the position illustrated in Fig. 1. A rapid reciprocatory motion is imparted to the rocker-frame 15 and hence to the tool carrier support 19 and the parts supported thereon, viz., the burnishing irons 23 and 23, the holders 25, 25, the carrier 27 and the carrier holder 29 while the shoe is turned by the operator to bring the different parts of the sides and toe of the edge of the sole in contact with the working faces of the burnishing irons 28 and 23. As the edge of the shoe is passed around in contact with the burnishing irons, said burnishing irons will tip to assume a position substantially as illustrated in Fig. 2 on the toe of the shoe in which figure the toe of the shoe is illustrated in dotted lines, and as the edge of the shoe is passed around in contact with the working faces of the irons by the operator, the irons will rock upon their pivots 24: and 24; and the carrier 27 will rock upon its pivot 28, so that the working faces of the irons will at all times assume a position about tangential to the edge of the shoe sole. The tipping of the carrier upon its said pivot 28 and the tipping of the irons upon their pivots 24 and 24 make it possible for said irons to assume the position set forth quickly and easily, so that the edge of the shoe will be quickly and nicely operated upon and burnished. The tipping of the irons upon their pivots, hereinbefore set forth, is for the purpose of allowing the working faces to assume a tangential position to the edge of the shoe sole.

In addition to the change in curve or outline of the edge of the sole longitudinally thereof, there is also a change in the edges of the soles of boots and shoes laterally thereof, as in passing from the toe to the ball of the shoe and from the ball of the shoe to the shank, and in order to keep the burnishing irons in alinement with and tangential to the edge of the sole the carrier 2'? turns, with its holder 29, upon the stud 30, and the burnishing irons 23 and 23 turn, together with their holders upon the studs 26, 26. Thus the Working faces of the burnishing irons will automatically as sume posit-ions tangential to the edge of the shoe sole and also will assume positions in alinement laterally with the edge of the shoe sole.

When the fore part has been completed and it is desired to burnish the edges of the shank portions of the sole, the shank burnishing iron 50 is brought into operation by means of the mechanism described in said Patent No. 931,558, whereby the tool carrier support is given a rotation of 180 and the shank burnishing iron with its holder is brought into the position occupied by the fore part burnishing irons in Fig. 1, viz, in front of the shank 18, the fore part burnisln ing irons occupying the position formerly occupied by the shank burnishing iron. The operator then passes the edge of the shank portion of the sole along the working face of the shank burnishing iron 50 on opposite sides of the shoe. During this operation the shank burnishing iron tips upon the pivot 51 and the holder rocks upon its pivot 53,

so that the working face of the'shank burnishing iron will always be tangential to the edge of the sole longitudinally thereof and will also be in alinement with the edge of said sole laterally thereof.

It is desirable in all classes of work that the pivotal axial lines of the burnishing irons should be close to the edge of the sole which is being burnished and in some styles of shoes it is desirable that the pivotal axial line of the shank burnishing iron should be in alinement with the working face of said burnishing iron, or even a little below said face, and in order to accomplish this latter result a modified form of burnishing iron, illustrated in Fig. 9, is employed. Referring, now, to this modified form of my in-- vention it will be understood that 56 is the burnishing iron, 57 the holder therefor and 58 a shank integral with said burnishing iron and constituting a pivot which is rotatably mounted on a holder, the median axial line of said shank 58 extending transversely of the working face of the iron 56 and substantially in alinement with a portion of the working face of said iron.

It will be noted that in applicants device the pivotal axial line of the burnishing iron holder lies in a plane extending transversely of the path of travel of the carrier and intersects the working face of the burnishing iron and this is the preferable construction in a device of this character, because if such plane does not intersect the working face of the burnishing iron, said iron will swivel around the pivotal axial line of the holder and the edges of the iron will cut into the sole or into the upper and spoil the work.

.That portion of the working face of the burnishing iron which contacts, when in use,

with the outer edge of a shoe sole is known the bed face of said burnishing iron. In applicants device, as will be seen by reference to Figs. 7 and 10, this bed face lies on opposite sides, respectively, of a plane extending transversely of, intersecting and at right angles to the working face of said burnishing iron and is adapted to contact simultaneously with different parts of a straightsole edge located at a substantial distance apart longitudinally of said sole edge, and furthermore, that the pivotal axial line of the burnishing iron and holder, while being at right angles to each other, are parallel to said plane.
